FOLDABLE PHONOGBAPH-HOBN.

Specification of Letters Patent.

Patented Nov. 12, 1907.

Application and April 22. 1907. Serial No. 369.497

To all whom it may concern:

Be it known that JULrUs C. STOCKER and DARRELL A. WaLsn, citizens of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, and Mount Oliver, in the county of Allemusical instruments.

An object of the invention, is to provide a horn, ca-

pable of being collapsed, whereby the same may be carried in the pocket at the time of transporting the machine to which the horn is to be attached, or upon shipment or storage of such horn, vwhere it will be seen that a large number may occupy a small floor space.

A further object of the invention is to provide a collapsible horn, made up of telescopic sections, said sections having means whereby they may be securely locked to each other when in use, and to provide means for holding said parts from displacement when the horn is not in use.

Another object is to provide a horn extremely simple in construction, strong, durable and therefore inexpensive to manufacture.

In the drawings: Figure 1 is a side elevation of my horn collapsed. Fig. 2'is a section therethrough on the line 22 in Fig. 1. Fig. 3 is an end view. Fig. 4 is a side elevation of the horn extended. 'Fig. 5 is a vertical longitudinal section therethrough. Fig. 6 is a detail section. Fig. 7 is a modified form.

Referring specifically 'to the drawings, 10 denotes the horn, which comprises the mouthpiece 11, thesections I 12, 13, 14, 15, 16 and the bell 17, all being constructed section 13; this operation is continued throughout the remaining sections of the horn. I

Hinged to the bell 17, as at 2 0, is a closure 21 which is provided opposite the hinge 20 with a clasp 22 adapt ed to engage the bead 17 of the bell 17, when the horn is collapsed. -At 23 on the inside of the bell 17, and adjacent the hinge 20 is a spring 24 which serves to hold the closure 21 in an open position after the clasp 22 has been disengaged from the bead 17.

At 25 is shown a cap which I place on the other end of the section 17 when the horn is collapsed, thus it will be seen that when the sections of the horn are collapsed they are .held within the bell 17 by the hinged closure 21 at one end, and the cap 25 at the other.

In the modified form of my invention shown in Fig. 7 springs 24, are stamped out of the sections 11, 12, 13, 14, 15 and 16, and work through a slot 25 therein.

What is claimed is:

1. A collapsible horn comprising telescopic sections, the sections having slots formed therein and located to lie outwardly of theadjacent sections when the horn is extended, springsconnected with said sections and engaged in the slots, said springs lying normally in position to engage the adjacent sections to hold the horn in extended position, and being movable through the slots out of said p0sition, a hinged closure for the outer of said sections a spring carried by the outer section and arranged to hold the closure in an elevated position when the sections are extended, and a removable closure for the opposite end of the outer section.

2.. A horncomprising a plurality of telescopic sections,

including a bell section, a removable closure on one end of hell section, a hinged closure on the other end or said bell section, a spring carried by said section and bearing against said closure to hold the closure in an elevated position, and means for holding the closure in operative position. v a

3. In a collapsible horn, the combination with telescopic sections having slots formed therein and located to lie outwardly o! the adjacent sections when the horn is extended, of springs connected with said sections and engaged in the slots, said springs lying normally in position to engage the adjacent sections to hold the horn in extended position, and being movable through the slotsout of such position.

In testimony whereof we alllx our signatures, in presence of two witnesses.
